LCFS - IDIR Initiative Agreement Comments Component

**Description:**

As an IDIR IA Analyst, IA Manager, or Director, I need to add and review comments on an Initiative Agreement so that I can maintain a record of discussions, decisions, and collaboration activities related to the agreement.

**Wireframe:**[IDIR Initiative agreement page](https://www.figma.com/proto/K65eN4XSiapyobejHKBwny/LCFS---SIU-IDIR-IA-Dashboard-display?node-id=648-2648&t=LQq5hSu2n62zyX7L-1&scaling=min-zoom&content-scaling=fixed&page-id=648%3A1450)

**Purpose and benefit to user:**

The comments component provides internal Ministry staff with a standardized communication and audit history mechanism within the Initiative Agreement record while ensuring users can clearly distinguish between internal and public communications.

**Acceptance Criteria:**
